I've always (since switching) described it as such: ganon has an answer for every situation. It's like playing rock paper scissors; if your wall is built well enough, you can even appear to have two options covered at very close to the same time. It's pretty cool. Problem is, at a certain level, you have to pick your option first, because the opponent can position themselves in a way that, due to ganons startup, he has to do something about the threat of an approach. If ganon doesn't pick his defensive option in this time frame, then they'll just get hit. Problem is, the opponent doesn't actually have to commit to any of these potential things. When people are attentive enough to bait your jab and punish with 40+% and an edgeguard situation, the game gets very very hard. You end up in a multitude of "damned if you do, damned if you don't" scenarios, and in todays meta, non-commitment is at an all time high -_-
Melee used to be about "you pick some option and i'll pick some option, and one of us will win because style" but now it's all heavy neutral and deciding who has more patience, and who can stand going to the 3rd 4th or 5th intention rather than swinging early. And ganon just isn't well suited for that, because he has to swing at too many false images and his cooldown is too much to deal with that fact.
Cool thing is, if you're just plain smarter than everyone else by a large margin, you can tell when someone is being noncomittal, and find ways to hit them for it, but it still means they were being noncomittal in a spot where they could get hit, which is silly of them.
This description of neutral came about when i was training with PP 3ish years ago when i was still in college. So often i simply couldn't tell where i went wrong, trying to play neutral to the best of my ability. Sure, kevin was a far far better player, and my intentions may have been easier to circumvent than they are now, but once you deal with a character/player with a good enough dash dance, you'll find yourself swinging at images that may or may not be real, and recognizing how damaging that can be.
edit: to some, this may seem a defeatist attitude, but to those who have played a while, I view this as fully respecting my opponent to not rely on their inattentiveness to win matches. There just feels to me, a certain amount of arrogance or bravado where you believe that your opponent will either be outsmarted at least twice as often by you, or that they will have a lapse of focus at least twice as often in many matchups. But with as much on the line as there is now...it's just not fun relying on those things, especially if you're attentive enough to have the proper reads but playing a character too slow to capitalize on them.
